====================
10GbE Intel Wired LAN Driver Updates 2017-04-18
This series contains updates to mainly ixgbe with only one ixgbevf change.
Usha adds a check to ensure the creation of number of VF's is valid based
on the traffic classes configured, all to avoid transmit hangs.
Joe Perches reduces the use of pr_cont since the output can be interleaved
by other processes.
Tony cleans up the code overwriting the KX4 config, which is configured by
the NVM. Adds a check for MMNGC.MNG_VETO, to resolve an issue where we
were getting a link loss for the BMC when loading the driver.
Don fixes up SGMII x553 config details which were missed in earlier
implementations. Added support for x552 XFI backplane interface support.
Cleaned up an unused define, which was causing confusion on supported
devices.
Emil fixes a link issue on KR parts by making sure the default setting is
set. Refactors the code so that the code for allocating memory for the
list of MAC addresses that the VFs can use into its own function. Made
some code cleans to help readability and ensure notification of SRIOV
being enabled is done upon completion. Fixed an issue where if we failed
to allocate vfinfo in __ixgbe_enable_sriov() the driver would crash with
a NULL pointer dereference.
Philippe Reynes updates ixgbevf to use the new API for
{get|set}_link_ksettings.
Alex increases the headroom allocation when using build_skb() on a
system with 4K pages. Fixed an issue in ixgbe_dump() where we were no
longer clearing the status bit.

When there is no FID set for a specific packet, the HW will drop it.
However, by default these packets are useful to be delivered to CPU as
it can inspect them and program HW accordingly. So add this trap.
This would only ever happen when port is enslaved to an OVS master.
Otherwise, packets would be dropped during VLAN / STP filtering,
before FID classification.

So far, mlxsw_sp_port_vlan_set range is limited by
MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is
wrapped up by a helper function which actually does multiple calls
to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set
and use it always. That allows caller not to care about the range.

'mpt' variable:

mpt->mtt = mtt;
I think this warning is a false complaint. mpt is only used when
mr_res_start_move_to() return zero, and in all such cases it initializes
mpt. But apparently gcc cannot see that.
Initialize mpt to avoid the warning.

The DMA API debugging (when enabled) causes:
WARNING: CPU: 0 PID: 1445 at lib/dma-debug.c:519 add_dma_entry+0xe0/0x12c
DMA-API: exceeded 7 overlapping mappings of cacheline 0x01b2974d
to be printed after repeated initialization of the Ether device, e.g.
suspend/resume or 'ifconfig' up/down. This is because DMA buffers mapped
using dma_map_single() in sh_eth_ring_format() and sh_eth_start_xmit() are
never unmapped. Resolve this problem by unmapping the buffers when freeing
the descriptor rings; in order to do it right, we'd have to add an extra
parameter to sh_eth_txfree() (we rename this function to sh_eth_tx_free(),
while at it).
Based on the commit a47b70ea86bd ("ravb: unmap descriptors when freeing
rings").

I just found that when we had changed the Rx path to check for length
instead of the DD bit we introduced an issue in ixgbe_dump since we were no
longer clearing the status bits.
To correct this I am updating ixgbe_dump to look for the length bits in the
descriptor since that is what we are using in the Rx path.

This patch increases the headroom allocated when using build_skb on a
system with 4K pages. Specifically the breakdown of headroom versus cache
size is as follows:
L1 Cache Size Headroom
64 192
64, NET_IP_ALIGN == 2 194
128 128
128, NET_IP_ALIGN == 2 130
256 512
256, NET_IP_ALIGN == 2 258
I stopped at supporting only a cache line size of 256 as that was the
largest cache size I could find supported in the kernel.
With this we are guaranteeing at least 128 bytes of headroom to spare in
the frame. This should be enough for us to insert a couple of IPv6 headers
if needed which is likely enough room for anything XDP should need.
I'm leaving the padding for systems with pages larger than 4K unmodified
for now. XDP currently isn't really setup to work on those types of
systems so we can cross that bridge when we get there.

Avoid setting adapter->num_vfs early in the init code path when
using the max_vfs module parameter by passing it to ixgbe_enable_sriov()
as a function parameter.
This fixes an issue where if we failed to allocate vfinfo in
__ixgbe_enable_sriov() the driver will crash with NULL pointer in
ixgbe_disable_sriov() when attempting to free the vfinfo struct based
on adapter->num_vfs. Also it cleans up the assignment of adapter->num_vfs
since now it will only be set in __ixgbe_enable_sriov() and cleared in
ixgbe_disable_sriov().

As pr_cont output can be interleaved by other processes,
using pr_cont should be avoided where possible.
Miscellanea:
- Use a temporary pointer to hold the next descriptions and
consolidate the pr_cont uses
- Use the temporary buffer to hold the 8 u32 register values and
emit those in a single go
- Coalesce formats and logging neatening around those changes
- Fix a defective output for the rx ring entry description when
also emitting rx_buffer_info data
This reduces overall object size a tiny bit too.

We disable VxLAN offload when more than 1 UDP port is added to the driver,
since Skyhawk doesn't support offload with multiple ports. The existing
driver design expects the user to delete all port configurations and create
a configuration with a single UDP port for VxLAN offload to be re-enabled.
Remove this restriction by tracking the ports added and re-enabling offload
when ports get deleted and only 1 port is left.
